While planning our trip to the Mid-Atlantic region last year, we considered both Hershey and Gettysburg as possible stops in Pennsylvania to break up the drive home from the Jersey shore. Gettysburg won. But as we were driving across Pennsylvania in a downpour, I started contemplating how miserable it might be trying to tour a battlefield in the rain. (I hadn’t realized how extensive the indoor exhibits were at that time.) Then, suddenly, I saw an exit for Hershey and made a split-second decision to change the itinerary and add a stop at Hershey’s Chocolate World after all.
